INTRODUCTION

domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes.


In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a website, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.

Most of the people don’t about the term DOMAIN. We are often asked by beginners- what is the domain name? However, many beginners confuse domain name with a website or website hosting service. If you are just starting out, then all these different terms may sound too technical.

What is a domain name? This seems to be such a basic thing, but it’s not always THAT easy especially if you’re a beginner.

Creating a website? You need to get many things in place before it’s up and running. One of the prerequisites is a domain name. So…what is a domain name?

What Is Domain Name?


Domain name is the address of your website that people type in the browser URL bar to visit your website.

A domain name is essentially your website’s equivalent of a physical address. In the same way that a GPS needs a street address or a zipcode to provide directions, a web browser needs a domain name to direct you to a website.

In simple terms, if your website was a house, then your domain name will be its address.

Detailed explanation:

The Internet is a giant network of computers connected to each other through a global network of cables. Each computer on this network can communicate with other computers.

To identify them, each computer is assigned an IP address. It is a series of numbers that identify a particular computer on the internet. A typical IP address looks like this:

66.249.66.1

Now an IP address like this is quite difficult to remember. Imagine if you had to use such numbers to visit your favorite websites.

Domain names were invented to solve this problem.

Now if you want to visit a website, then you don’t need to enter a long string of numbers. Instead, you can visit it by typing an easy to remember domain name in your browser’s address bar.

Domain names serve to identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the numerical addresses used in the Internet protocols. A domain name may represent entire collections of such resources or individual instances. Individual Internet host computers use domain names as host identifiers, also called hostnames. The term hostname is also used for the leaf labels in the domain name system, usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as websites (e.g., en.wikipedia.org).

Domain names are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the realm identifiers used in the Session Initiation Protocol (SIP), the Domain Keys used to verify DNS domains in e-mail systems, and in many other Uniform Resource Identifiers (URIs).

An important function of domain names is to provide easily recognizable and memorisable names to numerically addressed Internet resources. This abstraction allows any resource to be moved to a different physical location in the address topology of the network, globally or locally in an intranet. Such a move usually requires changing the IP address of a resource and the corresponding translation of this IP address to and from its domain name.

Domain names are used to establish a unique identity. Organizations can choose a domain name that corresponds to their name, helping Internet users to reach them easily.

A generic domain is a name that defines a general category, rather than a specific or personal instance, for example, the name of an industry, rather than a company name. Some examples of generic names are books.commusic.com, and travel.info. Companies have created brands based on generic names, and such generic domain names may be valuable.

Domain names are often simply referred to as domains and domain name registrants are frequently referred to as domain owners, although domain name registration with a registrar does not confer any legal ownership of the domain name, only an exclusive right of use for a particular duration of time. The use of domain names in commerce may subject them to trademark law.

A domain name takes the form of two main elements. For example, the domain name Facebook.com consists of the website’s name (Facebook) and the domain name extension (.com). When a company (or a person) purchases a domain name, they’re able to specify which server the domain name points to.

Domain name syntax

A domain name consists of one or more parts, technically called labels, that are conventionally concatenated, and delimited by dots, such as example.com.

The right-most label conveys the top-level domain; for example, the domain name www.example.com belongs to the top-level domain com.

  • The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node example.com as a subdomain of the com domain, and www is a label to create www.example.com, a subdomain of example.com. Each label may contain from 1 to 63 octets. The empty label is reserved for the root node and when fully qualified is expressed as the empty label terminated by a dot. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation. Thus, when using a single character per label, the limit is 127 levels: 127 characters plus 126 dots have a total length of 253. In practice, some domain registries may have shorter limits.

  • A hostname is a domain name that has at least one associated IP address. For example, the domain names www.example.com and example.com are also hostnames, whereas the com domain is not. However, other top-level domains, particularly country code top-level domains, may indeed have an IP address, and if so, they are also hostnames.

  • Hostnames impose restrictions on the characters allowed in the corresponding domain name. A valid hostname is also a valid domain name, but a valid domain name may not necessarily be valid as a hostname.

Are domain names and websites separate things?

Think of a domain name as your phone number and a website on your phone. While they are connected, they are separate items.

You can change your phone (website) at any time, and still, keep your existing phone number (domain name), and just connect it to your new phone (new website).

Or, you can move your phone number (domain name) to a different phone service provider (domain name registrar), and still keep it connected to your existing phone (your website).

Confused yet? Let’s do a simple illustration:

  • I can purchase a new domain name (let’s say www.vaishnogsoftwares.com) and connect it to this website you are on right now. All the content on this site will not change at all.

  • I can build a brand new website elsewhere, and disconnect www. vaishnogsoftwares.com from this website, and reconnect it to the new website I’ve built elsewhere. So when you type in the web address, you will be taken to the new website.

The key is that your domain name is not permanently stuck with any specific website. 

How do Domains Work?

Domain names work because they provide computer users with a short name that is easy to remember. Users enter web addresses into the URL field at the top of their browser’s page from left to right. The domain name itself is read from right to left according to the naming hierarchy discussed below. This link provides directions to the network, which ultimately results in a successful page load at the client end of the transaction.

The common fictitious domain name, www.example.com, is comprised of three essential parts:

  • .com – This is the top-level domain.

  • .example. – This is a sub-domain.

  • www. – This is a sub-domain prefix for the World Wide Web. The original use of this prefix was partly accidental, and pronunciation difficulties raised interest in creating viable alternatives.

Many servers use a three-letter naming convention for top-level domains, and they are separated from sub-domains by a dot. The significance of the top-level domain is the most important for new users to grasp. It identifies the highest part of the naming system used on the Internet. This naming system was originally created to identify countries and organizations as well as categories.

The most common categories are easily recognized by new computer users, and they include:

  • .com
  • .org
  • .edu
  • .net
  • .mil

A significant expansion of the top-level domains occurred, and they now include:

  • .biz
  • .museum
  • .info
  • .name

Country codes are also easily recognizable to new users because the abbreviations are the same ones used for other purposes. The organization of the domain name hierarchy and the ability to reserve them for only one purpose has already undergone several modifications. Discussions and debates concerning the availability and affordability of domain names can be expected to continue.

Sub-domains are organized to the left of the top-level domain, and this is the part of the domain system that is most recognizable to humans. It is common to see several levels of sub-domains, and some countries developed specific conventions of organization to communicate information within their internal naming systems.

Domain names accomplish few things:

How to Choose a Domain Name?

Create a lasting first impression: A domain URL is the very first thing a prospective customer will see and is their initial interaction with your brand. A unique or memorable domain name will speak to what they want and stick in their head. An unfitting domain, on the other hand, can turn off prospective customers.

Define your brand: A domain name can be used to instantly speak to your brand, letting the customers know who you are and what you are selling. A relevant domain name can help key your customers in on your product, or a unique domain name can create a link that associates your name with your product.

Optimize SEO: Search engine optimization utilizes keywords in order to help your SEO rankings. Exact match domains are not necessary, but it is helpful to use a domain that is close.

Choose a name that’s easy to type and Pronounce: If people struggle to spell it or pronounce it correctly, it will affect the memorability of the name and hurt your brand.

Pick a name that can be turned into a brand: You don’t want exact and partial keyword match domain names because they’re too generic and very difficult to brand. You should also steer clear from numbers and hypens in your domain name-they’re too difficult to remember and pronounce.

Keep it short and simple: Long, complex domain names run a huge risk of being mistyped and misspelled. That’s just an unnecessary headache.

Avoid names that can be confused with existing brands. If you think you can piggyback on some other brand’s success, you’re hugely mistaken. Brand confusion will be the least of your concerns when you get used!

Use an appropriate extension: with the new TLDs rocking the internet, you’d think everyone’s  going for something as eye-catching as “.boutique”. Yet the prevailing advice among the marketers is to stick to the old good “.com”. merely because it’s the most recognized suffix outside the tech world. If you’re targeting a local market, then ccTLDs is probably a better choice for your business.

Choose a name that indicates what your business does: I recommend you that consumers what they can expect to find when they land on your site is a great advantage to any business.

How Do Domains Work?

Domain names work by acting as a shortcut to the server that hosts your website.

Without a domain name, anyone who wanted to visit your website would have to enter the full IP address. But the problem is that an IP address is difficult for people to memorize or to include on advertising materials.

The Types of Domains

domain name registration

Just like every street needing a name and each house on it needing a number to receive its post, all devices connected to the internet needed to have a specific descriptor that allowed the traffic to be sent to the correct device.

In order to form a rudimentary virtual address book, computer scientists created the Internet Protocol Address System. It assigned a unique 32-bit or 128-bit string of digits, called the IP address (i.e. Internet Protocol address) to each computer or website so that they could all be distinguished.

Of course, trying to memorize the IP address of every site you often visit is not simply a burden but completely impossible for adept internet users. That is why computer scientists also devised a domain name system that assigned a unique name to every IP address, making it easy for any visitor to connect to a site.

When people think of a website, the standard ‘.com’ pops into their mind. Although it is, in fact, the most common extension, there are different types of extensions available for use.

There are, actually five extensions that you can use with your desired domain name, however, some of them are only available if you are running a specific kind of website.

Top-Level Domains (TLDs)



top level domain registration

Back in the 1990s, the Internet Assigned Numbers Authority (i.e. IANA) released six top-level domains.  These top-level domains (TLD) became known as domain name extensions and represent the highest level in the Domain Name System hierarchy. They include:

  • .com: shorthand for commercial, .com was the first top-level domain in common use. While .com was initially created for use by commercial organizations, restrictions on this were not stringent. By the mid-1990s, .com had become the most popular and commonly used type of top-level domain for businesses, websites, and email.

  • .net: shorthand for network, .net was created expressly for institutes that partook in network technologies such as an internet service provider or an infrastructure company. Like with .com, the restrictions meant to limit .net to networking purposes, was never upheld and it became one of the more popular top-level domains, with many seeing it as a close second to using the .com top-level domain.

  • .edu: shorthand for education, .edu was made for educational institutions. Although it was intended for universities everywhere, the TLD .edu became associated with only educational centers in America. Schools from other countries will use .edu in conjunction with their country-level domain, which we will discuss further below.

  • .org: shorthand for organization, .org was created for nonprofits. As we’ve seen with these other top-level domains, such intentions were often not upheld or enforced over time. These days, .org is used as a top-level domain by nonprofits, for-profit businesses, schools, and communities.

  • .mil: shorthand for military, .mil was created expressly for U.S. military branches. Unlike the other different types of top-level domains, this restriction is still upheld. Now, it is quite common for .mil to use second and third-level domains in conjunction with the .mil TLD.

  • .gov: shorthand for government, .gov, like .mil, was restricted for American federal governmental agencies and personnel use only. These days, .gov is used by governmental agencies, programs, cities, states, towns, counties, and native American tribes.

Country Code Top Level Domains (ccTLD)

The next type of domains are country code top-level domains. As can be inquired from the name, these domains are technically tied to different countries, with each one having its own ccTLD, however, it is not required to use one of them if you are in a specific country.

These domain extensions are useful if you are building a site in a specific country and want your visitors to know that they have arrived at the right place. For example, companies out of the United States can use the .us extension and ones located in Lithuania could use .lt.

Here are some ccTLD examples:

Note that: In order to register most ccTLDs you will need to provide documentations proving that you are residing in that country.


Generic Top Level Domains

Generic Top Level Domains

Although this is more of a definition than a type of domain, it is considered as a different variation of a TLD. Therefore, you could classify it as a top-level domain as well.

  • Despite there being over 1500 gTLDs available to register, there are 21 generic top-level domains within the root zone, which is the highest level of the domain name system structure. Thus, these 21 gTLDs make up the vast majority of all types of domain names. They include the following 4 sub-categories:
    Generic (.com, .net, .org, .info), domains that can be used for general purposes.

  • Generic restricted (.pro, .biz, .name) domains that can only be used for their specific purposes.

  • Sponsored (.edu, .gov, .int, .mil, .aero, .cat, .asia, .mobi, .coop, .travel, .tel, .jobs) domains that can only be used by businesses involved specifically with that industry.

  • Infrastructure (.arpa) which was one of the original top-level domains used to help with the DNS infrastructure. 

Second-Level Domains

second level domain

Second-level domains are a step below the previously mentioned TLDs in terms of the domain hierarchy. The best way to describe it would be with an example. In www.vaishnogsoftwares.com, “vaishnogsoftwares” is the SLD (i.e. Second-Level Domain).

There are also country code second-level domains such as:

  • .co.uk – commonly used by companies in the UK

  • .gov.au – used by governmental institutions in Australia

  • .ind.br – used by industries in Brazil

Third Level Domains

third level domain

These domains are below the SLDs within the domain name hierarchy. They are not considered to be full domain names in and of themselves, but as a part of a domain name. For example, in www.vaishnogsoftwares.com, the “www” part is the third level domain.

It is no longer required to have www. as a part of a domain name and thus third-level domains are not necessary for a domain to function properly. You can connect to our site with simply typing “vaishnogsoftwares.com” in the address bar.

The main reason why you might need a third-level domain is if you are planning to add a subdomain. For example, you want to add a store to your site, so you create the subdomain “store.yoursite.com”.

Technical requirements and process

In the process of registering a domain name and maintaining authority over the new name space created, registrars use several key pieces of information connected with a domain:

  • Administrative contact. A registrant usually designates an administrative contact to manage the domain name. The administrative contact usually has the highest level of control over a domain. Management functions delegated to the administrative contacts may include management of all business information, such as name of record, postal address, and contact information of the official registrant of the domain and the obligation to conform to the requirements of the domain registry in order to retain the right to use a domain name. Furthermore, the administrative contact installs additional contact information for technical and billing functions.

  • Technical contact. The technical contact manages the name servers of a domain name. The functions of a technical contact include assuring conformance of the configurations of the domain name with the requirements of the domain registry, maintaining the domain zone records, and providing continuous functionality of the name servers (that leads to the accessibility of the domain name).

  • Billing contact. The party responsible for receiving billing invoices from the domain name registrar and paying applicable fees.

  • Name servers. Most registrars provide two or more name servers as part of the registration service. However, a registrant may specify its own authoritative name servers to host a domain’s resource records. The registrar’s policies govern the number of servers and the type of server information required. Some providers require a hostname and the corresponding IP address or just the hostname, which must be resolvable either in the new domain, or exist elsewhere.

A domain name consists of one or more labels, each of which is formed from the set of ASCII letters, digits, and hyphens (a-z, A-Z, 0–9, -), but not starting or ending with a hyphen. The labels are case-insensitive; for example, ‘label’ is equivalent to ‘Label’ or ‘LABEL’. In the textual representation of a domain name, the labels are separated by a full stop (period).

What is a subdomain?

sub domain

A subdomain is basically a child domain under the main domain name. For example, videos.wpbeginner.com is a subdomain of wpbeginner.com.

Once you register a domain, you have the permission to create subdomains for it by yourself.

Subdomains are commonly used by websites to create child-sites under the same domain name. For example, a business website can create a subdomain for their blog or their online store as store.example.com or blog.example.com

Final Words

It’s extremely important to have an idea about how domains work and picking the right domain name for your business. A domain name is a long term investment for your business as it is the first thing your customers will see. A domain is like the seed that will grow your business.

What is country level domain?

ccTLDs use just two letters and are based upon international country codes, such as .us for the United States and .jp for Japan. They’re often used by companies that are building dedicated sites for specific regions and can be a good way of signaling to users that they’ve arrived at the right place.


What is Generic Top Level Domain?

GTLD is essentially a top-level domain that doesn’t rely on a country code. Many gTLDs are intended for a specific use-case, such as .edu which is aimed at educational institutions. That said, you don’t have to meet any specific criteria to register a gTLD, which is why a .com domain might not necessarily be used for commercial purposes.

Other examples of gTLDs include .mil (military), .gov (government), .org (for non-profits and organizations), and .net, which was originally designed for internet service providers (ISPs) but is now used more widely.

What is the meaning of Second-Level Domains?

You’ve probably seen these domain names before. We’re talking about a domain that sits directly below a top-level domain name. We’re not going to get too technical here because it’s easier to show with examples, particularly when it comes to country codes.
For example, British companies occasionally use .co.uk instead of .com, and it’s a perfect example of a second-level domain. Another second-level domain is .gov.uk, which is often used by governmental institutions, and .ac.uk, which is used by academic institutions and universities.

What is Subdomain?

Subdomains are useful because they don’t require webmasters to purchase an additional domain name to create divisions within their site. Instead, they’re able to create a subdomain that effectively points to a specific directory on the server. This can be super useful for campaign sites and other types of web content that should be kept separate from the main site.
For example, Facebook uses developers.facebook.com to provide specific information for web and app developers who want to use the Facebook API. Another great example is support.google.com

What is Free Domain?

There are also free domain names that you can get from different website builders such as WordPress.com, Squarespace, Weebly, etc.

Free domains are not good for long term business goals or if you wanting to have your own unique branding. We recommend paying a few bucks and getting your own.
